With Pennsylvania Rate Caps Expiring, Bridesburg Foundry Selects EnerNOC Energy
Supply Management and Saves $40,000 in First Six Months

BOSTON, Nov. 3, 2009 (GLOBE NEWSWIRE) -- EnerNOC, Inc. (Nasdaq:ENOC), a leading
provider of clean and intelligent energy solutions, today announced that
Whitehall, PA-based Bridesburg Foundry, one of the largest bronze and aluminum
foundries on the East Coast, has selected EnerNOC's Energy Supply Management
services to secure favorable energy contracts in advance of the expiration of
Pennsylvania rate caps.

Bridesburg began working with EnerNOC in 2008. Prior to that, Bridesburg was
enrolled in a demand response program, but was unhappy with the results.

"[The other provider] didn't deliver what they were promising us," recalled Tom
Druckenmiller, Plant Manager for Bridesburg. "They charged us for monitoring
equipment, and the payments we received were minimal. We were skeptical [about
joining another DR program, but] the EnerNOC people were very reliable and
resourceful right from the start. They clearly knew the business and the ins and
outs of demand response, as well as energy procurement, so we knew we had the
expertise we needed."

Although Bridesburg receives significant payments for their participation, the
financial upside is only one of the benefits. Bridesburg executives cite the
fact that the DR payments came without a lot of investment of the company's time
as one of the primary benefits of working with EnerNOC.

"EnerNOC DR is really almost too good to be true," said Vince Rivetti, President
of Bridesburg. "They made the whole process really easy. And in the end, we earn
significant annual payments - far beyond what we were earning with our previous
demand response provider."

In addition to the financial benefits, Bridesburg leverages its free basic
access to PowerTrak(R), EnerNOC's energy management software, to help better
manage its energy consumption at the foundry.

"In the beginning, PowerTrak helped us identify which furnaces were using the
most power, and to get a clear picture of where our energy was being used," said
Druckenmiller.

With a successful demand response partnership underway and electricity rate caps
scheduled to expire on December 31, 2009, Bridesburg turned to EnerNOC to
provide strategic advice that would enable the company to secure favorable
energy procurement contracts that align to their risk tolerance and achieve
significant savings through competitive supply contracts.

"EnerNOC came to us with a proposal that lets us pay 30 percent less than what
we were paying," explained Rivetti - savings that totaled approximately $40,000
in the first six months. "They talked to us about our business and our goals.
They looked at our current bills. And they came back with a proposal that
matched our needs and saved us a lot of money."
